LINo'rYPE-MACHINE.

To all whom it may concern: V

Be yit known that vI, ANDREW E. MARK- wnLLa citizen of the United Stat-es, and resident ot' St. Louis, Missouri, have invented certain new and useful Improvements in Linotype-Machines7 ,of which the following isa specification containing a full, clear, and exactdeseription, `reference being had to the accom an fine drawings formin a art Y c e; a

hereof. i My invention relates to improvements in linotype machines, the object of my invention` being to construct the back jaw of a first elevator of a linotype machine in such manner asyto receive division plates, which platesare arranged to forni slotsin the slugs for-the reception of ruleswit-liout the employment of special matrices as has been done heretofore.` v y For the above purposesmy invention consists in certain novel features of construction and arrangement of parts as willbe hereinafter vmore fully described, pointed,

out in the claims and illustrated by theaccompanying drawings, in whichj Figure l` is a vertical sectional elevation ,of

a portions-of the metal pot, a portion ofthe mold disk, portion of the tirst elevator withthe frontv jaw thereon and my improved first elevator back jaw and-parts `carried thereby in positions to cast a slug; Fig. 2

`is a front elevation of a portion oi' the mold disk and mold base plate carried thereby and illustrates the back jaw of the first elevator' removed `from Lthe elevator proper and in position relative to` the mold baseplate for casting a slug; Fig. 3 is a rear face view of the complete baci; jaw of the first elevator;

.y Fig. 4; is a sectional` elevation ltaken approxi- 10` mately on the line 4 4 of Fig. 2; Fig.y 5 is a sectional elevation taken on the line `,5--5` otFig. 3, the clamping plate and division )lates bem' ren'ioved' Fw. 6 is a ers aective l b 3 t? Y of the back jaw proper; Fig. 7 is a perspecvtive ot' the removable section of the back jaw; and, Fig@ 8. is a perspective of oneof the division plates.

Referring by nume alsto the accompany-- ing drawings: l designates the metal pot rrecess 9.

is of less height or thickness, `rom front to rear, and provided with liners'jthavingiii-- jaw 7, a portion 8 of which is detachably secured to the jaw proper. The reduced portion of the back jaw proper 7 is` recessed at 9 and the removable section 8 is provided` with a' vertical lange I0 of a size to till the The removable section| 8 is providedwvit-h slots l1 extending through the flange l0 and wit-li elongated openings lcommunicating with theslots ll tliroughwhicli a cap screw lis inserted and seated n the screw seats ll of the reduced portion of the jaw 7 ,thus permitting a slight vertical movementof the section 8 .relative-'to the jaw 7. 'Formed at each extremity ofgthe section Sand projecting Vfrom the lower margin thereof, are a 'pair of lugs. 15, each of which isprovided with an integral shoe 1G lhaving beveled taceslla arranged to seat in vdepressions formed inthe top face of the mold base plate as shown in Fig. Q and under the liners withthe bevel faces 16a, engaging the beveled faces et" of the liners` as shown in Fig. L1. `Formed in the section 8 are screw seats 17 longitudinally alning with apertures 1S iorniedin the-reduced portionof lthe jaw 7, and inserted through the openings-'1S and seated in the screw seats 17 are cap screws 19 embraced by extensile coil springs 20 the function of which springs is to normally hold the section 8 upwardly against the jaw 7. j

The rear face ot' the section 8 is recessed at 521 and in said recessed portion 2l is a'longi- I tudinal groove 22 and formed through said. recessed portion 2l isa number ot' screw yseats Q3. A clamping plate Q-t is ar 1'anged I i., i l, to be secured tothe section S in the recess 21 b f means of the ca i screws Q5 and formed ran ed to be seated in thegroove-26 formed .v in

-andwith a flange 31 arranged to be seated in t efforward face of the clamping plate the groove22 4formed in the section 8 of the back jaw. \Each of the division plates' 271is iprovided with a flange 32 projecting downwardly from its lower face.

l The jaw 6 and mold base plate 3 are provided with the usual grooves for receiving and holding projections carried by the mat- .rices.` Asshown inFig. 1 of the drawing,

the matrix 33 is of theordin'ary construction, that is a matrix carrying two letters, and further the matrices employed are of the type in which only a Nshallow groove' is formed in which the character is formed.

Asshown in the drawings, the division,l plates 27, 28 and 29 areA of 'diiierent'lengths as required to form and space the slots in the slugs 'unequal distances apa t'. 'The division plates 28 are arranged ,to produce a 'slug of the desired length and the division plates 29 are arranged to completely fill the opening -between the upper face of the mold y base plate and the clampingplate. The division plates are of .lengths determined by the point system, a set of each variety of which Il furnish with the attachments.

Heretofore .in forming slugs with slots to receive brass rules, special matrlces were employed in which the ligure or letterwas in l the bottomof an unusually deep slot'instead' of being located in a shallow slot as in the ordinary matrix. When such matrices were employed a special mold was required being of less height or thickness from front to "rear and the slots were formedv by special matrices or division plates, without slots.-

46 In operating, under the old system, the operator lays out or casts up 'his table employing in the assembler scale,`a strip 'ot' paper with marks to indicate the required rules.

My improved attachment for linotype ma- I chines is arranged to holdthe devices, for

forming the slots in the slugs, in the mold base plate, and employs `the ordinary two letter matrix, thus it is obvious a greater variety of v faces may appear `the 32 when being positioned in the mold base plate, the springs 2O permit a slight vertical movement of the section 8 and clamp '24 y relative to the mold base plate and when the section .8 and clamp, together with the division plates, are inserted in the proper position on the mold base plate and back jaw proper, the bevel faces 16a of the shoes 16 5 engaging the under bevel faces 4 of the clamping liners .tendt'o normally hold anges 32 against themold base plate, -when the slug is being cast.

f By reason of the reduced thickness from I. 4

front to .rear of the top capor plate 3", the flanges on the division'plates may be made of greater y length than heretofore, thus deeper slots may be formed, in the slugs which permit of the use of heavier rules. I have found vin practice the rule as at resent used is easily bent out ofshape and o r this reason I- construct my 'device so that heavier rules may be employed.

.I claim:

1. 'The .combination in a 'linotype machine, of a mold base plate with a tirst elevator back jaw constructed of two pieces vertically movable relative to'each other, a4

plate carried by one ofthe ,pieces of the ack jaw and division plates arranged to be secured inthe back jaw by said clamping plate. 4

2. In a linotype machine, the combination with amold base plate of a first elevator, a back jaw carried by the elevator, a section of ywhich lback jaw is movable vertically relative to thejaw proper, a clamping plate carriedby the movable portion o the backr jaw, there being longitudinal slots formed 1n the meeting faces. of the movable section of the back jaw and the clamping plate and division plates havino flanges arranged to be embraced and heldtby the slots formed in the clamping plate and back jaw.

3. In a linotype machine, the combination with a mold base-plate 'of a first elevator,'a back jaw carriedl by the elevator, a section ofl the back ljaw bein separable from the jaw proper and capab eof a slight vertical movement relative to the jaw proper, a clamping plate arranged to be secured to the separable section of. the 'back jaw, division plates for forming slots in slu s carried by the back jaw and held in p ace by said clamping plate.
